lavfi has been considered to be stable for a while now, so it is enabled
in most configurations. Supporting avplay without lavfi requires a lot
of nontrivial ifdef mess for no good reason.
4.9 was released precisely nine years after the first GCC version with
autovectorizer (4.0) and six years after the first GCC version with
`-ftree-vectorize` default to enabled on `-O3` (4.3). We've given GCC
enough time to fix those bugs.
FATE passes here on a x86-64 machine with both GCC 4.9.2 and 5.3.1.
Some optimization hotspots benefit greatly from this change, especially
those without handwritten assembly. For instance, the main function in
vf_phase is now 1.6x faster (1.2x overall) on my machine.
Or when building in-tree.
Also don't try to remove src on distclean in these cases.

The configure detection is bumped to X265_BUILD >= 68,
since API version 68 corresponds with the x265 1.8
release tarball. The warnings inside x265 about
12-bit being experimental were removed prior to API
version 72 a short time later. At this time of
writing, X265_BUILD is at version 80.
12-bit support in the HEVC standard was approved in
October 2014 as part of HEVC Version 2 and published
in January 2015:

This uses a new MMAL feature, which limits the number of extra frames
that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can
be defined as positive or negative number. Positive numbers are
absolute, and can lead to deadlocks if the user underestimates the
number of required buffers. Negative numbers specify the number of extra
buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers.
Set a gratuitous default of -11 (N=10). This is much lower than the
firmware default, which appears to be 96.
This is backwards compatible, but needs a symbol only present in newer
firmware headers. (It's an enum item, so it requires a check in
configure.)
AVX2 support was introduced in Yasm 1.2.0 and NASM 2.10, and the
oldest versions currently supported are Yasm 0.8.0 and NASM 2.03

It dropped the old headers, but the replacements are already available

If links don't work, fall back to using the full source path as was
previously done.
This should fix build failures with MSVC.

Fix configure to set DST_PATH to the Windows style path when building with MSVC
Fixes ticket #5180.

Previously the full source path was embedded inconsistently in the debug
information between in-tree/out-of-tree builds.
The 'vpath %.inc' becomes necessary for finding
libavfilter/all_channel_layouts.inc in out-of-tree builds.
The full source path is still embedded in the debug information, but
it's now independent of whether building in-tree or out-of-tree.
The biggest improvement of this patch is that gdb now always searches
for the path relative to the source directory. It still also searches
for the full path.
Previously it searched only for the full path in out-of-tree builds,
making the debug information generated by Debian's buildds rather hard
to use.

Before this patch trying to enable only https by issuing
--disable-protocols --enable-protocol=https --enable-gnutls
does not enable https, and
--disable-all --enable-protocols
does not enable libavformat and the protocols component.
Now the default-enabled options are set after the explicitly
disabled/enabled options are evaluated.
If an explicitly enabled option cannot be enabled configure
will fail printing an error message.
Updates libkvazaar to pass the exact frame rate to Kvazaar by setting
the numerator and denominator separately instead of a single floating
point number. The exact frame rate is needed for writing timing info to
the bitstream.
Requires Kvazaar version 0.8.1.
